When azimuth control is enabled for 1-of-N by ticking the ENABLE AZIMUTH CONTROL
tickbox, its menu slightly changes:
Individual relays in the 1-of-N group can be
assigned individual azimuths, which
represent the primary direction for the state,
when corresponding relay is switched on.
There is no requirement on particular values
of the azimuth, their order nor span.
In Menu→Heading, if any of ARXC is set to a group with azimuth control enabled, headers to
columns corresponding to ANTENNA #2 and ANTENNA #3 are not static labels anymore, but
they are pull-down menus. When opened, ANTENNA #x is always the first option, followed by a
names of those ARXC groups, which have azimuth control enabled. In the following screenshot,
for ANTENNA #2 an ARXC group with the name 1OF3@1 is selected; for ANTENNA #3 the
pull-down is opened and displays the list of available options:
If ARXC group is selected instead of ANTENNA #x, its name is given by the name of this group
set in its respective Menu→System→ARXCx, and it cannot be changed in this menu. All other
settings apply in the same way as for normal ANTENNA #x, i.e. ENABLE determines presence
in the main screen's selection, OFFSET is added to the primary direction corresponding to state
of relays within the group, BIDIR is observed both for display and control, LINK determines
presence in the selection within the LINK group (either locally or through LAN).
BEAMWIDTH influences only display; azimuth control input is always decoded into the group
state which has the closest primary direction, taking into account both OFFSET and BIDIR.
ARXC group is azimuth-controlled only if this group is selected as the current Antenna in the
main screen.
